Grendel is often read alongside existentialist ideas, particularly those associated with Jean-Paul Sartre. Gardner wrote the novel with that philosophical conversation in mind, and students pick up on it quickly. The trouble is that they often reach for the word "existentialism" long before they can explain it.

A typical weak essay says Grendel is an existentialist character because he thinks life has no meaning. That blends existentialism with nihilism, and it skips the harder question of what a person does after concluding the universe offers no built-in purpose. Catching that confusion is one of the most useful things a grader can do.

You do not need to grade students as philosophers. You do need to decide how much philosophical accuracy the assignment expects. A ninth-grade honors class and a college seminar should not be held to the same standard.

Whatever the level, the essay should stay anchored in the text. A claim about existential freedom means little unless the student shows a specific moment in the novel where Grendel wrestles with choice. Philosophy should serve the reading, not replace it.

Separating philosophy from literary analysis

Give students a clear expectation that they are writing about a novel, not summarizing a philosophy lecture. The best essays use a concept as a lens, then show how Gardner dramatizes, mocks, or complicates it. Essays that define terms for two paragraphs and then mention the book briefly need a different kind of feedback.

• Defines any philosophical term in one clear sentence and uses it consistently
• Distinguishes between Grendel's beliefs and what the novel as a whole suggests
• Points to specific scenes, not general impressions of the character
• Recognizes irony, including moments when Grendel contradicts his own outlook
• Avoids treating the novel as a straightforward endorsement of any single view

Feedback for muddy philosophical claims

When a student mixes up terms, resist correcting with a lecture in the margin. Ask a question that pushes them to test their own claim, such as whether Grendel actually acts as though he has freedom. Students revise better when the correction comes from their own reasoning.

If you are grading a large set, a tool like GraideMind can flag essays where the philosophical claims are asserted but never tied to evidence, based on the criteria you set. You still read the essay and decide whether the flag is fair. It just helps you find the pattern faster.

Watching for borrowed ideas

Philosophical language is easy to borrow from a search result or a study guide without understanding it. Ask for the student's own example whenever a big term appears. A student who really grasps the idea can explain it through the novel in plain words.

Short in-class writes are helpful here. A ten-minute paragraph on what Grendel believes about meaning, written without notes, shows you what students actually understand. It also gives you a baseline for judging the longer essay.

Rewarding students who complicate the reading

The best philosophical essays do not settle for one neat answer. They notice that Grendel claims to reject meaning while being deeply moved by the Shaper's songs. Building your rubric to reward that kind of tension encourages students to read against their first impression.

Share one or two excerpts of strong student reasoning with the class after grading. Hearing how a peer handled the same difficulty is often more persuasive than any comment you write. It also shows that this kind of thinking is within reach.
